Frequently asked questions
- DPI (dots per inch) is metadata — it tells printers how to scale the image on paper. Changing DPI does not add new pixel information. It affects print size, not screen sharpness. A 300 DPI image printed at the correct size will look sharper than a 72 DPI version of the same pixel count.
- Most passport and visa applications require 300 DPI at the specified print dimensions.
- 300 DPI is the standard for most document and photo printing. 600 DPI is used for high-quality print work like fine art or detailed technical diagrams.
